Title: Tire with sub tire having protrusible anti-slipping spikes
Inventor: NAKAMURA KINYA
IPC: B60C11/16
Filed: 1981-05-27
Abstract: PURPOSE:To enhance a spike effect by protruding out anti-slipping spikes provided through a tire tread in a sub tire in the inside wall of the tire tread and  by pneumatically protruding and withdrawing the anti-slipping spikes. CONSTITUTION:A sub tire consists of a tread section 2 and side wall sections 3 extending from both sides of the tread section 2. The sub tire is formed integral with an inside wall of a tire tread 1 at the side wall sections 3. Anti- slipping spikes 4 which are supported at one end, are grasped airtight with the tire tread 1. An air pipe 6 is connected to a space 5 defined within the sub tire. Discharging the air from the space 5 through the air pipe 6 allows an air pressure in a tread interior 8 to compress the sub tire, thereby protruding the anti- slipping spikes 4 out. Supplying a compressed air back from the pipe 6 withdraws the anti-slipping spikes 4 into their original positions.

Filed: 1990-03-29
Abstract: PURPOSE:To shorten the processing time of a whole system by providing plural storage means which hold communication history between central processing units and can be freely written and read from each of plural central processing units. CONSTITUTION:In the case a higher rank CPU 11 collects the communication history stored in a dual port RAM 15 between an intermediate rank CPU 12 and a lower rank CPU 13, the lower rank CPU 13 copies the contents of the dual port RAM 15 to the dual port RAM 16 before it sends a response to the intermediate rank CPU 12, and puts interruption into the higher rank CPU 11 at timing of the lower rank CPU 13 sends the response to the intermediate rank CPU 12. The higher rank CPU 11 refers to the contents of the dual port RAM 16 as processing for that interruption. Accordingly, the higher rank CPU 11 can collect the communication history between the intermediate rank CPU 12 and the lower rank CPU 13 at real time. Thus, the processing time of the whole system can be shortened.

Title: Manufacturing method of silver (2) oxide cell
Inventor: HIROTA MASAYUKI
IPC: H01M4/08
Filed: 1981-05-31
Abstract: PURPOSE:To control the increase of internal resistance during storage by impregnating an alkaline aqueous solution in the surface layer of a two-layer positive electrode consisting of silver (II) oxide and silver (I) oxide layers, depositing lead hydroxide, incorporating it in a cell, oxidizing lead hydroxide in the cell during storage, and forming a lead dioxide layer on the surface of the positive electrode. CONSTITUTION:A two-layer positive electrode in which a silver (I) oxide layer 3 is formed around a silver (II) oxide layer 2 by reducing the surface layer of the press molding substance consisting of silver (II) oxide is immersed in alkaline aqueous solution and the alkaline aqueous solution is impregnated on its surface layer. Then the positive electrode is immersed in a nitrate aqueous solution and lead hydrooxide is deposited on its surface. As described above, when the positive electrode 1 which impregnates the alkaline aqueous solution is immersed in the nitrate aqueous solution, lead hydroxide is deposited on the surface of the positive electrode 1. Besides, when the positive electrode 1 in which this lead hydroxide is deposited is incorporated in a cell, lead hydroxide is oxidized during storage and becomes lead dioxide. Since this lead dioxide is in the highest oxidation state, it is excellent in oxidation resistance. When a lead dioxide layer is formed on the surface of the positive electrode 1, this cell has small internal resistance and prevents the internal resistance from being increased during storage.
